The competition in the machining industry is extremely fierce. Sometimes, the key lies in whether the machining task can be completed in a short time while ensuring quality. Brass, aluminum, and steel are common machining materials. But which material has a faster machining speed? In this article, we will compare these three materials and attempt to answer this question.
Properties of brass, aluminum, and steel
Brass is an alloy that contains copper and zinc, so it has good conductivity and thermal conductivity. In contrast, aluminum is a metallic element with light weight, high strength, and strong corrosion resistance. Steel is an alloy composed of carbon and iron, which has high strength and good wear resistance. From a comprehensive perspective, compared to aluminum, brass has slightly lower strength but better conductivity, thermal conductivity, and corrosion resistance; And steel has higher strength and wear resistance.

Brass vs Aluminum vs Steel:Comparison
Usually, the speed of machining depends on the hardness and characteristics of the material, as well as the machining equipment and process used. Among the three common materials, brass, aluminum and steel, we will compare the following three aspects
Comparison of raw material characteristics
Brass, aluminum, and steel are common metallic materials that have different physical and chemical properties, as detailed in the following comparison table:
Characteristic | Brass | Aluminum | Steel |
---|---|---|---|

Melting Point (°C) | 900 – 940 | 660 | 1370 – 1530 |
Thermal Conductivity (W/m·K) | 109 – 125 | 205 | 43 – 50 |
Electrical Conductivity (MS/m) | 17 – 30 | 34 – 65 | 10 – 20 |
Young’s Modulus (GPa) | 96 – 123 | 68 – 79 | 190 – 210 |
Yield Strength (MPa) | 170 – 450 | 40 – 550 | 215 – 230 |
Tensile Strength (MPa) | 300 – 600 | 70 – 700 | 400 – 550 |
Hardness (Brinell HB) | 60 – 140 | 15 – 120 | 120 – 600 |
Corrosion Resistance | Moderate to High | High | Low to Moderate |
Magnetism | Non-magnetic | Non-magnetic | Magnetic |
Flammability | Non-flammable | Non-flammable | Non-flammable |
Alloying Elements | Mainly Copper and Zinc | – | Iron, Carbon, and other elements |
Brass is an alloy composed of copper and zinc, which is dense and has good corrosion resistance and electrical conductivity. Aluminum is a lightweight metal with a relatively low density, good thermal conductivity and corrosion resistance. Steel is an iron alloy rich in carbon, dense, rich in strength and durability.

Comparison of machining speed
In actual production, the machcining speed of brass, aluminum, and steel is influenced by various factors, such as material hardness, material and shape of cutting tools, technology and level of machcining technology, etc. The following is a comparison of the machining speeds of the three materials in common machcining processes such as milling, turning, drilling, and stamping
machining Method | Brass | Aluminum | Steel |
---|---|---|---|
Milling | 50 – 150 mm/s | 100 – 300 mm/s | 30 – 80 mm/s |
Turning | 0.05 – 0.3 mm/rev | 0.1 – 0.6 mm/rev | 0.02 – 0.1 mm/rev |
Drilling | 15 – 60 mm/min | 50 – 200 mm/min | 10 – 40 mm/min |
Stamping | 80 – 300 strokes/min | 150 – 500 strokes/min | 40 – 120 strokes/min |
Under the same machcining conditions, brass has the fastest machcining speed among the three materials, followed by aluminum and steel. This is mainly because brass has lower hardness and indentation depth, making it easy to cut and mill
Factors affecting machining speed
The machining speed of brass, aluminum and steel is affected by a number of factors. Here are some of the main factors that affect their machining speed:
1.Material hardness
Material hardness will directly affect the machining speed. In general, harder materials require a slower cutting speed, while softer materials can adopt a higher cutting speed.
2.Cutting condition
Cutting parameters are directly related to the machining speed, including cutting speed, feed speed and cutting depth. Different materials require different cutting parameters to obtain the best machining results.
3.Tool selection
The choice of tool type and tool material suitable for the material will also affect the machining speed. Different materials may require different types and characteristics of the tool to achieve higher machining speed and cutting efficiency.
4.Tool selection
Choosing the tool type and tool material suitable for the material will directly affect the machining speed. Because different materials require different types and characteristics of the tool, in order to achieve more efficient machining speed and cutting efficiency.
5.Job design
The shape, size and complexity of the workpiece also affect the machining speed. More complex workpieces may take longer to process, while simple geometric shapes can be machined faster.
6.Machine tool performance
The rigidity, stability and power of the machine will also have an impact on the machining speed. High performance machine tools usually have higher cutting speeds and higher production efficiency.
